How to fetch all databases with name having upper case character after some word using MySQL?
For this, use regular expression. The syntax is as follows −
select * from information_schema.schemata WHERE SCHEMA_NAME REGEXP '^yourValue_+[A-Z]';
Let us create some databases −
mysql> create database bank_APP1; Query OK, 1 row affected (0.00 sec) mysql> create database bank_APP2; Query OK, 1 row affected (0.00 sec) mysql> create database bank_APP3; Query OK, 1 row affected (0.00 sec)
Here is the query to get all databases having upper case character after some word −
mysql> select * from information_schema.schemata WHERE SCHEMA_NAME REGEXP '^bank_+[A-Z]';
This will produce the following output −
+--------------+-------------+----------------------------+------------------------+----------+ | CATALOG_NAME | SCHEMA_NAME | DEFAULT_CHARACTER_SET_NAME | DEFAULT_COLLATION_NAME | SQL_PATH | +--------------+-------------+----------------------------+------------------------+----------+ | def | bank_app1 | utf8 | utf8_unicode_ci | NULL | | def | bank_app2 | utf8 | utf8_unicode_ci | NULL | | def | bank_app3 | utf8 | utf8_unicode_ci | NULL | +--------------+-------------+----------------------------+------------------------+----------+ 3 rows in set (0.00 sec)
